Step-by-step explanation:
To solve question 4, you have to work backwards. Plug 40.82 as C in the formula C = D x 3.14. It would now look like: 40.82 = D x 3.14. Divide 40.82 by 3.14 and you would receive 13 as the diameter. However, we are searching for the radius. The radius is half of the diameter. 13 / 2 is 6.5
To solve question 5, you'll need to use the formula C = D x 3.14. So far, we know D is 6. 6 x 3.14 is 18.84. Yet, we need to find the cost. Each foot costs $12.50, so that's what we multiply to 18.84. In the end, the cost is $235.50.
